Anna Thorne was a young Hero in the Delta 4 Hero team.
Like all other Heroes, Anna Thorne came into being in the Assembly Tower in Makuhero City, shortly before the creation of Jay Ratchet. Following her activation she was integrated into an unknown hero team, where she would receive training from one of the Elite members of the group.
Little is known about Thorne's actions following this point but it is known that she witnessed the death of a close female teammate in her original team, which greatly altered the rookie's perspective of being a hero.
Some time after this, when her team began to fracture apart, she requested to be transferred to the Delta 4 team to avoid the conflict.
Around 27 years after the present storyline, Thorne accompanied the recently restructured Delta 4 team to Danaria 7, where they were charged with protecting the planet's President, Caliga.
However, during a Blorphog Day celebratory appearance at a homeless shelter, an assassin attempted to take Caliga's life. Fortunately, Sharp was able to push her out of the way, though the bullet caught a weak spot in her armor and splintered her Hero Core, as well as causing her hydraulic fluid reserves to puncture. Sharp passed away shortly afterwards in the arms of Sam Clank. Thorne stood as a witness to this and prevented a local news cameraman from filming the death, affording her teammate some degree of dignity.
In Thorne's earlier days as a rookie, she witnessed the death of a female teammate, an event that had a tremendous impact on her life and personality, arguably shaping her into the hero she became. She became very emotionally driven, involving herself completely in the heartache and needs of those around her. Thorne largely prevented her old team from falling apart and took on many responsibilities to the point where she filled the void left by her fellow teammate's passing.
